Abstract: Containers for storing fluids, especially carbon dioxide, under pressure in which a tubular component (1) made of a deformable material capable of at least 7 % elongation before fracture is preferably closed on a top plug (2) with a filling/emptying device (and any end plug) by crimping the open end(s) of the component over a circumferential shoulder on the plug(s). A primary pressure relief device comprising a poppet (14) with a piston section, a return spring (15) and a control orifice (19), tolerates and ejects dirt, prevents the formation of solide phase material and vents the contents in brief spurts so as to minimise loss. Desirably, a narrow helical conduit (7) connects the primary pressure relief device to the container interior and, by being in thermal contact with the tubular component, chills the contents during venting so as to further minimise loss. One or more secondary pressure relief devices such as bursting discs may also be incorporated to vent substantially the whole contents in the event that the primary pressure relief device fails to maintain the internal pressure below a safe predetermined level. The construction allows the fitment of alternative adaptor assemblies (see figure 2) for various uses and lends itself to automatic assembly. The use of a heat storage substance is also disclosed.

Abstract: Apparatus for carrying out analyses comprising at least one incubation step and at least one separation step for separating a liquid phase which is insoluble in said liquid phase. The apparatus comprises a plurality of reaction vessels (2), making it possible to simultaneously carry out similar working sequence in the separate reaction vessels, each of which has a porous bottom (3) connected to a separate chamber (8), the reaction vessels being able to retain the reaction mixture during the incubation steps. According to the invention, there is provided a pressure regulating system, which creates a higher relative pressure in the chambers (8) than in the reaction vessels (2). This pressure difference prevents leakage from the reaction vessels to the chambers.

Abstract: The power drawn by a load (RL) from an A.C. network is controlled by an operational amplifier (OP1) and a power transistor (TR2). The operational amplifier makes the transistor leading when the voltage of its inverting input which is derived from said network, is lower than a reference voltage supplied to its non-inverting input. The pulses through the load take a form corresponding to the first and last parts of a sinusoidal half-wave. Their time lengths are shortened according as the voltage of the feeding network increases, and vice versa.

Abstract: An encoder is provided for encoding fixed length binary words into (VWL) encoded serial data in which each non-zero word comprises a start bit and an end bit of one state and a number of intervening bits of a different state, the number of such bits representing the magnitude of the word. In a preferred embodiment the coder comprises a multiplexer (10), a PROM (12) and a flip-flop (14). The PROM (12) provides a feedback signal comprising three parts - a control signal, a binary word representing the magnitude of the input word, and an output signal having either of two states. The feedback signal is repeatedly applied to the PROM (12) by the multiplexer(10). The PROM (12) responds by reducing the magnitude part of the feedback signal by one. Each time the cycle repeats, another bit appears at the output (22) of the coder as the output signal. Accordingly, the number of such output bits corresponds to the magnitude of the input word. Eventually, when the magnitude has been reduced to zero, the multiplexer selects a new word to apply to the PROM (12).
